I found the following diagram recently and I thought it was interesting: Unfortunately the source is a single book titled “Restructuring for Caring and Effective Education: Piecing the Puzzle Together” that contains a chapter by Knoster, Villa and Thousand. Apparently nobody quotes the content of it in any way around the web, and it’s without a digital edition, so I wasn’t able to evaluate the proper context and what the authors meant with each terms.
However, I find this valuable even in this unexplained form, so here it is:
While the original context seem education, the above seems more framed in terms of initial action around complex systems, which makes it interesting.
The aspect I find valuable about this diagram is that it highlights the outcomes of missing a piece, more than saying that you really need all of them. In other words, you can still achieve change without steps, but you have to consider the negative effect that comes out of it and address it.
